anorectal manometry

A procedure that measures the tension in the external and internal anal sphincters, as part of a work-up for constipation or faecal incontinence.
 
Procedure
After evacuation of the bowel with enemas, a metal tube is inserted ± 15 cm through which a second, thinner tube is inserted, which has an inflatable balloon at its end; the pressure response of the rectal wall to the expanding balloon is measured.

Patients who have symptoms of altered continence at 3 months (or who score above 6 on the Wexner scale) should be seen at a dedicated gynecologic or colorectal surgery clinic, (46) where they can receive a more detailed clinical evaluation and undergo anal manometry (during resting and forced squeezing) or endo-anal ultrasonography.
In patients with fecal incontinence, for example, anal ultrasound is the cornerstone of treatment, but anal manometry, EMG, and pudendal nerve assessment "round out the evaluation," she said at a symposium on pelvic floor disorders sponsored by the Cleveland Clinic Florida.
An anal continence assessment performed 3 months post partum found no differences in anal manometry or neurophysiology between the groups.
Patients were evaluated using standardized clinical and paraclinical investigations such as anoscopy, colonoscopy, defecography, colon transit time, endoanal sonography and anal manometry. 81 patients with diagnosis of hidden rectal prolapse or prolapsing circumferential hemorrhoids were selected for surgical treatment by Delorme operation, stapled transanal rectal resection (STAAR) or 30 mAmp electrotherapy (13,14) according to the preference of consultant surgeon and clinical findings.
No changes in anal manometry, sphincter integrity upon endoanal ultrasound, or pudendal nerve terminal motor length were noted.
Patients in this series were identified using a complete urologic evaluation, sigmoidoscopy, anal manometry, anal sonography, and pudendal nerve terminal motor latency studies.
* Anal manometry. This test measures pressure and compliance in the rectum and anus and may identify impaired rectal sensation.
